This video presents a newfound solution to the plastic crisis currently occurring. A promising study conducted by a team in Switzerland discovered an alternative for plastic that disintegrates into harmless sugars in the environment. It is produced from non-edible plant parts, specifically a long chain-like molecule called lignin that is found in plant cell walls. Furthermore, unlike the previous failed alternatives to plastics scientists have come up with, this new alternative has properties that are so close to the conventional plastic we use; it is strong, blocks gases, and can resist high temperatures. Follow along as we go into further detail about this breakthrough! This video was made by McMaster University students Aya Selman, Lavanya Sinha, Pooja Sharma, and Youmna Sinjab in collaboration with the Demystifying Research McMaster Program.
